  • A dual-beam spread spectrum signal based on directional modulation is proposed to increase the difficulty of the wireless communication tapping. The transmitted signal is not only associated with the spread spectrum sequence but also with the azimuth angle of the receiver. Therefore, this signal is a space spread spectrum signal modulated by the azimuth angle. Simulation results show that the proposed signal offers a safety method for the data transmission compared with the traditional spread spectrum signal.
